MACHINEFOR MAKING WRAPPING BANDS Application filed November 8, 1927.

This invention relates to the production of ;paper bands having their end portions provided with adhesive material such as disclosed in Letters Patent No. 1,589,503 issued to me June 22, 1926.

Bands of the type referreil to are useful for many purposes such as the wrapping of laundry articles or the wrapping of packages of money. If the adhesive coated ends of the bands curl it is frequently dificult to properly moisten the adhesive coating and to affix it properly to'the portion of the band on whiclnit is laid. As is well known, when adhesive is appliedito paper and dried the contraction of thegum. when drying, curls up the paper.

One of the objects of invention is to provide bands of the character referred to with tabs having .a minimum tendency to curl.

Another object is to provide bands of the type illustratedin said patent with accurately connected and located tabs.

\Vith the above mentioned objects in view the invention consists in the method and ma chine substantially as hereinafter described and claimed.

Serial No. 231,902.

Similar reference charactersindicate similar parts or features in all of the views.

Referring first to Fig. 1 a suitable frame work 12 is provided, said frame work supporting a shelf or bracket 13 and supporting 65 a shaft 14 for a roll of paper web material (1. Also supported by the frame work are guide rolls 1516, a guide roll 17, a suitably driven roll 18, and an idly rotating pressure or pinch roll 19. 60

Supported by the bracket 13 is a stand having a pin 21 for a roll of a gummed strip 6, a suitable friction strip 22 being also mounted on the pin 21.

Supported by the bracket 13 is the'base 23 "66 of the moistening device, the'latterincl'uding a water chamber 24 (Figs. 1 and 6) to which water is supplied by a pipe 25 from a suitable reservoir or other source ofsupply26.

Mounted on the walls of the Water chamber 10 24 are two plates between which the strip Z) is drawn as hereinafter described. Theupper plate 27 has a wide slot'28' through which a wick 29 in the water chamber projects. The strip'b passes under a'roll 30, over aroll ms 31 and-under a'roll 32 havingannular guide ribs properly spaced as indicatedin Fig. 5, said roll 32 being'sup'portedby arms 3 l.

Referring again to Fig. 1 vertical guides 35 are provided inwhich is 1nounted a shaft is!) 36 having a pressure roll 87 the purposeof which will presently be explained.

Said shaft 36 is free to descend'by gravity.

The lower plate 27 onthe water chamber, and over which the strip 6 is-drawn, has a lip 38 which serves to steadythe upper por tion of the wick 29, and to also deflect or direct any suplus water that might bedrawn along by the strip?) back intothe water chamher. The saidplate 39 has a curved rear edge 60 40 and is slotted to provide an opening 41 (Fig. 7). It also has a surface rib 42 which serves to guide the strip 7) sothat only the portion of said strip, which is to overlap and be connected to the web a, will'be moistened, as indicated by comparing Figs. 2 and 3.

It is important that the gummed strip 6 shall have no tendency to curl. Thereforegit has its coating broken explained in Letters Patent 1, 368,080 to VanSluys, issued Febrtr i ary 8, 1921. Usually the machine as illustrated in that patent treats a wide gummed web which is afterward cut into strips. It is such a strip as this which is employed in carrying out my invention.

In operation a. roll of the strip Z), carried by the stand 20, is threaded through the nioistening device as illustrated b Figs. l and 6 and is adhesively attached to the surface margin of the roll or web of paper a and the two strips or webs o b are then drawn in the direction indicatd by the arrows in Fig. 1, such drawing being mainly effected by the rolls 18ll. As has been mentioned, the cover plates of the nu istening device guide the strip 7) in such ma- ..r relatively to the mounting of the web roll (L that the strip 3) does not overlay its tul width on the web a but only a n'iarginal portion thereof as illustrated by 2 and and it is only this lateral portion ot the strip 1 which is to overlap the margin ot the web a. that passes in contact with the moistening wick 29. This is to prevent the softening of the gum which is on that portion of the strip 7) which projects beyond the margin of the web a from being mo stened so as to conequently require somewhat prolonged dry The pressure roll 37 is of a width to press the moistened margin of the strip I) on to the margin of the web a and such connection noes not require much time for drying before the combined web a and strip 7) are transversely cut to produce such articles as illustrated by Fig. 11.

In view of the tact that any suitable cutting mechanism may be employed. it is not necessary to illustrate the same. In fact the transverse cutting might be eflected by manually operated shears. Furthermore. the method of producing the articles such as illustrated by Fig. 11 might be entirely carried out or practiced manually.

Fig. 1 illustrates that the united or combined strip 7) and web a travel for a considerable distance, after leaving the point of pressure together by the roll 37, about the rolls 15-16 and to the drawing rolls l8l9. This provides ample space for the location of the moistener device and also gives ample time for the adhesively secured margin of the strip and web to dry before being transversely cut.

While I have illustrated a strip 7; as conn ected to only one margin of the web a, it is obvious that a duplicate me hanism could be employed to connect a similar strip to the other margin of the web so that the web would have strips 72 attached to and proiecting from each edge thereof. hen such duplicate mechanism is employed the web a is to be longitudinally severed approximately its mid-width so that each transverse cutting of the web and bands would produce two of the wrapping bands illustrated by Fig. 11.

Having now described my invention, I claim 1. A machine {or adhesively uniting two strips of paper in marginal overlapping relationship one of which strips has an adhesive coating, comprising means for causing the strips to travel from two sources of supply, means for moistening a limited lateral portion of the coated strip, and means for pressing the two strips together.

2. A machine of the character described, having means for feeding a web of paper. means for guiding a gummed strip to position on a marginal portion of said Web, means for applying moisture to the gummed strip before its contact with said web, and means for simultaneously severing the web and strip transversely.

A machine of the character described, having a support for a web of paper, means tor guiding a gummed strip to position overlapping and projecting from a margin of said web, means for moistening that portion of the gummed strip which is to overlap said web. and means for pressing together the overlapping portions of the web and strip.

4-. A machine for uniting two lengths of paper to prepare them for transverse cutting into duplex sections, said machine including means for applying a narrow strip of gummed paper to the marginal portion of a trave ing wide strip of paper, means for applying moisture to one of the strips to efi'ect adhesive uniting of the strips, and means for pressing said strips together.

In testimony whereof I have afiixed my signature.
